What Size Or Gauge Is A Bicycle Chain Metric?

What size is a standard bicycle chain?

All modern bicycle chains are made to the “one-half inch pitch” standard, meaning from rivet to rivet is nominally 0.5 inches. The sprocket teeth are cut for this same one-half inch standard to accept bicycle chains. However, this does not mean all makes and models of chains are interchangeable.

How do I know my bike chain size?

Add the multiplied chainstay length, the divided number of teeth for the chainring and rear sprocket, and add 1 (or 2.5 cm). The result is the ideal chain length for your bike. For example, you’d add 32.5, 13, 7 and 1 to get 53.5. The length of the chain should be 53.5 inches or 135.89 cm.

What size is a 9 speed chain?

9 speeds. Chain width is about 6.7 mm. In a pinch, a 10 speed chain can be used. Still, narrower chain is more expensive, doesn’t last as long and will cause a bit slower shifting… but it will work.

How is chain width measured?

Diameter is given for chains and bracelets with a cross section of the cylinder. Width is measured when bracelets and necklaces are “flat” or have a shape different from a cylinder. Length is measured always with the clasp, as a real length of fastened bracelet or chain.

Are all bicycle chains the same size?

Are all bicycle chains the same size? No, all bicycle chains are not the same size. Size varies on the bike’s numbers of sprockets, speeds, the distance between the front chainring and rear cogs, and the number of teeth on them.

What is the most common bike chain size?

Chains come in 3⁄32 in (2.4 mm), 1⁄8 in (3.2 mm), 5⁄32 in (4.0 mm), or 3⁄16 in (4.8 mm) roller widths, the internal width between the inner plates. 1⁄8 in (3.2 mm) chains are typically used on bikes with a single rear sprocket: those with coaster brakes, hub gears, fixed gears such as track bicycles, or BMX bikes.

How do I know what speed my bike is?

Multiply the front gear number by the rear gear number to get the number of speeds. For example, if you have two front gears and five back gears, you have a 10-speed bike. If you have one front gear and three back gears, you have a 3-speed bike.

How many links do I need in my bike chain?

Bicycle drive chain length A new bicycle chain usually comes with 116 links. This is long enough for the biggest chainrings and for most distances of rear wheel from front chainrings. So for optimal length a new chain is usually shortened from the 116 links that come in the box.

How is chain wear measured?

Another ballpark method for checking chain wear is by measuring it with a ruler. Pick a rivet and line it up at the zero mark. Count 24 more rivets and your last rivet should be at the 12″ mark of your ruler. If it is off by more than 1/16″ your chain is stretched to the point of replacement.

How often should I change my bike chain?

The 2,000-Mile Rule. To avoid this accelerated wear of your cassette and chainrings, a general rule of thumb is to replace your bike’s chain every 2,000 miles. Mind you, this is just a starting point. No two chains will wear at exactly the same rate because no two riders treat their chains the same. 4

Are 9 and 10 speed chains compatible?

10-speed chains have the same inner/roller width as 9-speed chains while being narrower. Therefore, a 10-speed chain meets the compatibility requirements because it has enough inner space for a 9-speed sprocket and doesn’t cause rubbing due to its slimmer profile.

Is 1mm chain too thin?

Most chains are 1mm to 1.5mm, which is sturdy enough to hold most small to medium sized pendants. If you go below 1mm, just keep in mind that a thinner chain is less strong, even if it has a daintier look. Pendant Weight: The heavier the pendant, the stronger the chain you’ll need in order to wear it.

How thick is a 2mm chain?

2mm is approximately equal to 1/16 inch.

How do you measure a log chain?

Measure from one end of an individual link to the other end of that same link. Now count the links in the chain, and multiply that half of the chain length; this is because the links overlap, so this shortens the overall possible length. Also measure the width of the link’s individual side to find its diameter.
